No, you cannot turn off RAS with software. Power steering plus can be added or turned off after sale (many people turn it off due to its overboosted numb feel, but few add it)

That’s a great description. And this is exactly what it feels like: a little bit of slip that points the nose just right. Definitely exploitable at mountain pass speeds, not just on track.

You will certainly notice it but whether you like that sensation or prefer to play with the accelerator and steering yourself is a personal choice.

I’ve said in another thread that I think it is good - I’m glad I specified it on my car - but it pushes that sublime ‘cornering on tip toes’ sensation unique to 911s just a little further out of reach.

So there's no additional hardware for power steering plus, just programming? This can be added later by the dealer? I know the option price was quite low which would justify this.

Correct. The PS+ just changes the setting of the electric steering ratio at lower speeds. That's it.

It doesn't change the steering ratio - just the level of servo assist (can park with your little finger while you use cell phone and sip latte).

I think this has been posted before, but Henry Catchpole had some thoughts as well. More of a second hand account than anything, but food for thought. Go to 6:57 mark (embedding won't allow me to do it)

Is tire wear affected by RAS?

I think RAS is partly blamed for fast rear tire wear on the GT3.

It's a definite yes for a regularly tracked car, no question. Hence why it's on GT cars, which are incredibly complex examples of the 911. The GT cars also integrate the RAS better, which was a complaint on 991.2 S/4S cars and supposedly improved to some extent on the 992, although I can still feel the RAS working. The point is you might get a better feeling car in real world use without it.

Personally I've yet to find a car/suv/truck I can't U-Turn or parallel park in a busy city (Seattle) and I would argue there's a certain gravitas (and humor) in doing so in a 911 without the assistance options (PS+ and RAS).
Ha.. you should try an F80 M3. This car has legitimately the worst turning radius of an car i've ever driven. Parallel parking is still easy but the dang thing needs 4 full lanes to do a U turn. I've owned suburbans and big trucks and all in between and never had a problem like I do with the F80.

I’d be curious to see a comparison if turning radius between RAS and no-RAS. How much difference is there when making a u turn?

i drove a RAS car, and immediately noticed the u turn radius was a lot smaller than I would have expected.

my dealer actually tested that with my car... as it was the only RAS car they had gotten at the time... It was 3' less turning radius

The RAS is better on track and it save you *** on the road

feeling wise they are right but a panamera weight and size 992 when it loose its *** you have to pray to recover it without the RAS

RAS is needed because today's car are too big and heavy

that a why to fill the fun gap on modern cars you need 600HP ( at least the 992 S RAS PDCC I tested where i found the engine boring)

so to get fun or you risk your *** or you wait the 992Turbo or you get warranty void with tuning
(unless you live as a taxi driver and daily drive on the nurburgring ...) damn porsche developers...when a carbon tube small 911?

2SS/4S or GTS is a car for commuting in perfect relax and occasionally fun on track drive
for somethingelse you need more expensive versions but sure can you manage warp speed on the roads?

Obviously you've never driven a McLaren

@GratedWasabi you are right on both counts. Turning radius is great without RAS (and there is also no need for power steering plus). I can attest to the high-speed stability and lane-changing ability of the 992 without RAS. On Sunday morning I had a relatively clear run from Stuttgart to Munich on the A8. It is usually congested, but that day the left lane was mostly clear. I was running between 200 and 240 km/h (125-150 mph) effectively uninterrupted for 30 minutes (limited to 240 by the snow tires). I've never owned a car that is so easy to drive at those speeds. Of course you are always alert but it is not tiring as it is in some cars. Rock steady.

wow, that’s a pretty big difference.
